I don't recommend it at all
I don't recommend, you will pay so much for extra stress, they put so much pressure, the timing doesn't respond to the emergencies you could face in your trip, all they want is extra fees and only extra fees, the cars are not as expected, I really don't recommend it especially in Cairo Egypt, it is so expensive; using alternatives; will offer your better transportation experience plus you will save your money and especially your peaceful state.
